Description

The USP Marine MAX+ Performance Forced Air Duct is engineered specifically for Mercury V8 engines, addressing a common issue found in the factory air duct known as the "station wagon effect," where exhaust fumes are inadvertently drawn into the engine through the rear sides of the cowling. This phenomenon can result in power loss and decreased top speed and a potential increase in fuel consumption. The USP Marine MAX+'s innovative forced air duct effectively prevents this issue by channeling clean, ram air from the top of the cowling, ensuring that unwanted exhaust fumes are pushed away from the intake.


Designed with the 500R model in mind—recognized as the leader of the V8 family—this duct maximizes airflow to meet the engine's performance demands. Additionally, the 300R and 450R models will also benefit from enhanced airflow. Manufactured in the USA, the USP Marine MAX+ utilizes motorsports-inspired injection molding to create a lightweight yet durable material that withstands the rigors of daily boating and fishing. We have employed advanced scanning technology to ensure precise fitment to the V8 engine cowling. The result is a product made from high-strength materials known for their lightweight properties, exceptional durability, and impact resistance.


With over 20 years of experience in tuning forced induction engines, we understand the importance of maintaining optimal conditions for performance. The MAX+ duct increases ram air intake by over 50%, significantly reducing intake air temperatures, which is crucial for performance and engine life. During wide-open throttle (WOT) operation, particularly in warmer conditions, this enhancement can yield an impressive retention of 2-3 MPH in top-end performance, with even greater gains for boats exceeding 100 MPH.

In addition to its performance benefits, the motorsports-inspired design of the USP Marine MAX+ Forced Air Duct adds a striking and aggressive aesthetic to your Mercury V8 engine. Elevate your engine's performance and appearance with this exceptional forced air intake duct.
 
*****Please note**** The forced air duct comes painted with a primer color and must be painted your color of choice on both sides before installation. DO NOT BAKE TO DRY IT WILL WARP THE FORCED AIR DUCT.
